SynopsisThe remote Debian host is missing a security update.
DescriptionA security vulnerability was discovered in the Dovecot email server.
When reading FTS headers from the Dovecot index, the input buffer size is not bounds-checked. An attacker with the ability to modify dovecot indexes, can take advantage of this flaw for privilege escalation or the execution of arbitrary code with the permissions of the dovecot user. Only installations using the FTS plugins are affected.
For Debian 8 'Jessie', this problem has been fixed in version 1:2.2.13-12~deb8u6.
We recommend that you upgrade your dovecot packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
